Han 2016.

Methods	RCT Method of randomisation: not stated Blinding of outcome assessors: stated as 'yes' Adverse events: none Deaths: none Dropouts: 4 in control group (2 refused and 2 dropped) ITT: no
Participants	Country: Republic of Korea 60 participants (30 in treatment group, 30 in control group) Non‐ambulatory at start of study Mean age: 68 years in experimental group and 63 years in control group Inclusion criteria: clinical diagnosis of stroke < 3 months after stroke onset, first‐ever stroke, dependent ambulation with severe gait impairment (FAC < 2), and sufficient cognition to understand procedures and provide informed consent Exclusion criteria: contraindications for RAGT therapy; cerebellar or brainstem lesions that could affect autonomic or balance function; musculoskeletal disease involving the lower limbs, such as severe painful arthritis, osteoporosis, amputation, or joint contracture; and other concurrent neurological diseases (e.g. Parkinson's disease, multiple sclerosis, etc.)
Interventions	2 arms: Experimental group: 30 minutes of exoskeletal robot‐driven gait orthosis training (Lokomat) and 30 minutes conventional rehabilitation therapy 5 times per week for 4 weeks Control group: 60 minutes conventional rehabilitation therapy. Physical therapy conducted by physical therapists certified in neurodevelopmental techniques was provided for balance and mobility 5 times per week for 4 weeks
Outcomes	Outcomes were recorded at baseline and after the 4‐week intervention; all outcome parameters were measured within 3 days before and after 20 sessions of training: Primary outcomes: brachial–ankle pulse wave velocity (baPWV, which evaluates arterial stiffness) and cardiopulmonary fitness Secondary outcomes: clinical functional outcomes, including basic ADL function, balance, gait functions, and motor functions of the paretic lower limb
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Method of randomisation not described.
Allocation concealment (selection bias)	Unclear risk	Allocation concealment not described.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	A physiatrist (rehabilitation doctor) who remained blinded to participant group and treatment throughout the entire study analysed outcome measures.
Incomplete outcome data (attrition bias) All outcomes	High risk	No ITT
